SYSTEM OF WATER DISTRIBUTION.

Application filed August 5, 1916.

To all whom it may concern:

Be it known that I, DILL CHAPMAN, a citizen of the United States of America, residing at La. Junta, in the county of Otero and State of Colorado, have invented a new and Improved System of Water Distribution, of which the following is a specification.

My present invention relates to an improved system of water distribution, and is particularly applicable for use in connection with railway passenger trains, for the purpose of supplying water for various purposes to each car of the passenger train from a central or main supply tank, preferably carried by the tender of the locomotive pulling the train.

The primary object of the invention is to provide a system of water distribution especially applicable for railway passenger train service which will provide a reliable supply of fresh water to be used for drinking, culinary, or other purposes, and which system is capable of extension or contraction accord ing to the number of cars used in the train. By the utilization of my system, a great saving is attained, both as to time and labor. In the present mode of watering cars of a railway passenger train, the services of several men are required to fill the tanks of the separate cars, and this mode of filling the tanks requires the expenditure of much time and labor, and which will be readily understood by those familiar with railway traffic. When a passenger train is equipped with my system of water distribution, many delays are avoided, and objectionable features are eliminated, and a comparatively perfect and reliable system of Water distribution is provided.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed and arranged according to the best mode I have so far devised for the practical application of the principles of my invention, but it will be understood that the embodiment and arrangement are subject to variation within the scope of my claim without departing from the spirit of my invention.

Figure 1 is a diagrammatic illustration of a railway train, showing the locomotive and two passenger cars equipped with my system of water distribution.

Fig. 2 is a vertical, sectional view showing the main reservoir carried by the locomotive Specification of Letters Patent.

tender, and one of the tanks, two of which are carried by each car, and the flexible hose coupling between the tender and a car or between two cars, is also illustrated in this view.

My system of water distribution is adapted for passenger trains comprising various numbers of cars, but for convenience of illustration, I have shown the locomotive as 1, and the two passenger cars designated as 2 and 3. Of course, the number of cars may be increased or decreased within limits of the capacity of the engine or locomotive 1.

The locomotive tender 1 I equip with a main reservoir 4:, and this reservoir supplies the water tanks 5 and 5 carried by the passenger cars. If desired, only one tank may be used for each car, but preferably a tank 5, and a similar tank 5 are carried at the respective ends of the cars. For dining cars, or other cars adapted for special purposes, the arrangement ofithe water tank will be varied as understood.

The reservoir 4 is located at a point on the locomotive tender as high as can be secured, without infringing upon the limited height of the locomotive or passenger cars, and this reservoir is adapted to be filled with water and is provided, for sanitary purposes, with a cover 6. An outlet pipe 7 in the reservoir is controlled by a valve 8, and this pipe is adapted to supply water from the main reservoir through the flexible coupling indicated at 9, 10, 11, and 12, and the coupling connects this outlet pipe7 with the main pipe 18 carried by each car. The flexible coupling between the tender and first car, as well as between other cars, is of standard type, and comprises the usual hose coupling similar to the steam or air couplings between the cars of standard railroads.

The main pipe 18 is preferably located on the interior of the cars and runs along the corner of the car between its side wall and the floor, and preferably in juxtaposition to the steam pipe line of the railway train, in order to prevent freezing of the water in winter. The main pipe is controlled by a pair of valves 13 and 13*, one located at each end of the car, and when the car is detached from a train, these valves being closed, the supply of water is retained in the tanks 5and 5. Each tank is fitted with a branch pipe as 14, 14 by which the tank is connected to the main pipe 13, and a valve 15 of the valves except the valves 16 and the last valve 13 at the rear end-of the train open, it will be seen that a supplyoit' water is maintained throughout the entire train of cars, and when the water is drawn from one tank, the supply is automatically replenqshed as 1on as the water remains 1n the reservoir 4. d?referably,-the valve or faucet 13 at the rear end ofthetrain, is cracked,

or left slightly open, in order to permit an infinitesimal waste of water therethrough-in order to insure a continuous circulation.

However, under ordinary conditions it will be seen that as water lsdrawn from the var-1- ous tanks 50nd 5, a clrculatlon Wlll be induced as-a matter of course throughout the entire system. lVhen a car is tobedetached from a train, =the hose coupling is released at 10 at both ends of the car, the two valves 13 :and 13" having previously been closed. Thus a car may be cutout from a train and still retain its water supply. 3 In coupling up the cars to make up a train, the

distributed and the entire train equipped with the required supply.

From .the above description taken in connection with my drawings it is evident that I have provided asystem of water distribution for use in railway equipments, which fulfils the functions of a comparatively per-- feet 1 system and will secure the objects here- ;tofore stated, and eliminates the numerous objections to the present system of water distribution throughout passenger trains.

hat I claim is:

A system of water distribution for railway passenger trains comprising a mainele- .vated reservoir, smaller sealed tanks carried by the several carsofthe train the :topsof which are below the bottom of the reservoir, a main pipe from the reservoir .to the several ears,=and branch pipes iiromthe main pipe to the tops of the tanks whereby the tanks are automatically kept full and the water inwhich isunder pressureof the full weight of thewater in the reservoir.

In testimony whereof I ailix my signature.
